I just noticed: no more crashes! Thanks, KDE team!

The only crashing problem I'm having now, and it's a regular one, is that
one of the plasmoids I have installed crashes plasma when I shut kde/X/
the-computer down, so it doesn't actually shut down until I close the
It's a plasmoid from kdelook, so not really a main kde problem, *EXCEPT*
for the poor plasma design choice of running all of plasma single-
threaded, so a single misbehaving plasmoid can either freeze or crash the
entire plasma-desktop. That *DESPITE* the fact that the trend these days
is to have separate sandboxed processes for everything, see chrome/
chromium, and firefox is headed that way -- but still the quite new
plasma just /had/ to be designed so a single misbehaving plasmoid would
kill it, even tho they were deliberately making it extensible and
inviting people of all sorts of skill levels to design plasmoids for it,
the VERY SAME reason chrome/chromium did the sandboxed-process thing and
firefox is headed that way! They had the opportunity to design plasma
for robustness in that regard from the very start, but didn't. Now they
have backward compatibility issues to worry about if they try to fix the
problem. Oh, well... <shrug>

FWIW, I'm VERY MUCH enjoying kde4 now that I switched away from kdepim
entirely, thus allowing me to set USE=-semantic-desktop. I had forgotten
what having a fast system was like, but now I'm remembering! =:^)

Why are you using so many dolphins? Dolphin doesn't really seem to be
designed for that sort of use -- if it was, it'd have options (as does
konqueror, performance section in the config) both to have separate
windows use separate instances (the memory settings, minimize memory uses
threads on the same instance so if one crashes they all do, while never
minimize forces separate instances for each window, so if one crashes,
it's just that window gone), and to keep instances preloaded, so they
don't take long to launch.
Or alternatively, do something like I do and use mc for sysadmin work,
and gwenview for images and video, so there isn't much left for dolphin
to actually do -- it's basically an enhanced file-open dialog, and as
such, it doesn't generally stay open that long anyway.

The last time I booted with akonadi, after I had migrated away from kmail
(the only thing I had that used it) but was still using akregator, so I
couldn't kill USE=semantic-desktop and unmerge the whole kit-n-kaboodle
as I eventually did, despite the fact that I had nothing actually needing
akonadi any longer and I've no idea what caused it to load, it started
using 97% of one core. Luckily I have four cores so one single-threaded
endless-loop doesn't really affect me that much, but when I saw that, I
tried to terminate (SIGTERM) it. Only it wouldn't terminate, I had to
Even tho I was actively searching for an akregator replacement in ordered
to get kdepim and thus the semantic-desktop junk off my system entirely,
that was enough akonadi misbehavior for me, and I deleted /usr/bin/
akonadiserver, added it to (PKG_)INSTALL_MASK and remerged the akonadi-
server package and restarted kde, just to be sure I didn't get any funny
errors. I didn't, and the irritating warning about nepomuk being off
went away as well. The headers or whatever might have been needed for
kdepim-common-libs, thus the dependency, but the binary certainly wasn't,
and if it was going to be so rude as to take all available CPU on a core
when I didn't even need it, it was going to get terminated and removed
from my system, WITH PREJUDICE!
Of course, at that time I didn't know that within about 12 hours, before
I restarted kde again, I'd have settled on a replacement for akregator,
got it setup, and unmerged both akregator and since that was the last
kdepim app I was running, all of the kdepim libraries, plus akonadi-
server, etc, as well. And after it was gone I could finally kill
USE=semantic-desktop and remerge kdelibs, dolphin, etc, without it.
As I said, the system feels lighter and faster, now! =:^) Maybe I'll try
semantic-desktop stuff again... someday... when even the disposable paygo
phones are a dozen-core-plus and come with half a terabyte of RAM! =:^)

What I really appreciate is that kde is customizable enough that those of
us who don't need semantic desktop can turn it off. =:^) (Same thing
with effects, too. Significantly, unlike gnome-3, those who don't have
fancy graphics cards, can turn off all the fancy effects and still have
the same shell, not a fall-back that they've removed much of the previous
functionality from, tho I have reasonably decent graphics and the effects
are for me another reason to like kde4. =:^) Too bad they couldn't have
used the same principles of robustness when designing plasma. =:^( )
